-    as described below.
-        This allows the paths being checked to be displayed relative to the
-    checkout root, and for path-specific style checks to work as expected.
-    Path-specific checks include whether files should be skipped, whether
-    custom style rules should apply to certain files, etc.

-      paths: A copy of the paths parameter -- possibly converted, as follows.
-             If this method changed the current working directory to the
-             checkout root, then the list is the paths parameter converted to
